Augering Answers
Leaking storage tanks, a long time environmental problem, are now being addressed nationally with cleanup regulations. Clearly, inexpensive and quick remediations are needed. This article...
Hydro Development on the Huallaga River in Peru
The proposed Chaglla Hydroelectric Project, is located on the Huallaga River in Central Peru, about 300 km north east of Lima. The available gross head of 870 m and regulated flow of 58...
Glen Canyon Environmental Studies Resource Response Analysis
The primary objective of the Glen Canyon Environmental Studies is to determine how the resources of the Grand Canyon respond to the operations of Glen Canyon Dam. Two levels of analysis...
The Effect of Sedimentation on Hydro-Developments
This paper will discuss two major impacts which are the hydro construction on natural stream sedimentation and the sedimentation related problems during hydro operation. The two types...
Improving Design of Small Hydro Plants
One objective of this paper is to show why certain features of many small hydro plants have given poor operational performance or experienced expensive maintenance problems. A second objective...
Milltown Powerhouse Rehabilitation
The Milltown Powerhouse and dam are over 80 years old. The powerhouse and other structures were built in 1906 and are owned by the Montana Power Company. The plant is located on the Clark...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Fire Protection at the Grand Coulee Hydro Project
In the fall of 1980 a rupture of one of the Project's 525kV transmission cables occurred and created a fire. Power from three Third Powerplant 700MW units was interrupted,...
RCC Pavement Construction and Quality Control
In October 1986 a 16,500 sq yd (14,300 sq m) roller-compacted concrete (RCC) pavement tank hardstand, the first of its kind in Europe, was built for the U. S. Army at Harvey Barracks in...
Determining Impacts of Sediment Using Cesium-137
Tecumseh Lake, in east-central Oklahoma, completed about 1934, has been identified by the Oklahoma Water Resource Board as a water supply critical to future development of the state. Aerial...
Optimal Pump Operation Using Nonlinear Programming
This paper focuses on the operational control problem of determining the optimal pump operation policy for a given distribution system. The optimal pump policy is defined as that schedule...
